Check out Alan's website, http://www.k0bg.com/ . It is the best one on mobile radio. Be sure to read the grounding section and the vhf options. He has some good info on the Larsen 2/70 Remember the 2/70 is a 1/2 not 1/4 wave. Check out the links he provides for a study on the different antenna's.

It is old, like of a vintage where the Chinese didn't know yet how to make good copies.

I don't recall the model number, but about a decade ago, I bought and used a Diamond dual band which broke when I went under a tree branch that was lower than I thought it was. I ordered another (to use the parts) which was advertized to be the same as but not made by Diamond and got an antenna with a beige base and a black coil. (It was the coil I needed and the one on that knockoff looked exactly the same) I replaced the coil and antenna worked fine after, so the rest of the replacement went into the junk box. I just remember that beige base coil looked totally different than the one on the Diamond--and I don't mean just the color. 73!

cjs, I hear you. Going by the images I find online, my base has the same shape and size that Larsen's black base of today has. Also, the separate gaskets that Larsen sells for their antennas fit perfectly. Knock-off or not, it works well and looks like it has weathered many a storm and tons of attempts to break (bend) it.

The original Larsen NMO 2/70 had an enclosed phasing coil, no base spring and a grey base, which usually fades to some indeterminate colour in the sun. Sound familiar? I have the same antenna on one of my older vehicles.

I prefer the enclosed phasing coil to the open coil; the whip doesn't seem to be as boingy as the open-coil version on the wifoid's Honda.
